This is a continuation-in-part of application Ser. No. 308,410, filed Sep. 19, 1994, and now abandoned.

BACKGROUND OF THE INVENTION

.[.Buttery.]. .Iadd.Butterfly .Iaddend.sponge mops have been used with great success as an efficient cleaning tool for many .[.yes.]. .Iadd.years.Iaddend.. The feature of the mop which allows its sponge to pivot closed, thereby squeezing fluid from a fully soaked or soiled sponge, has been a major advance in the industry. The .[.buttery.]. .Iadd.butterfly .Iaddend.sponge mop patent, U.S. Pat. No. 2,643,407, is representative of this type of mop.

It is similarly well-known to employ a brush or other abrasive member at the end of a .[.buttery.]. .Iadd.butterfly .Iaddend.sponge type mop, in order to allow for a separate scrubbing action, along with the smooth surface cleaning action and absorption capability of the relatively soft sponge mop. Such mops, as shown in the prior .[.an.]. .Iadd.art.Iaddend., routinely contain a brush device attached to the head or front of a mop, at right angles to the sponge member. The mop arrangements shown in U.S. Pat. Nos. 2,701,888, 2,858,557, and 2,916,754 are illustrative of these features. The configuration of these mops, however, employ cumbersome brush attachments which can not be removed or be removed easily, do not allow for interchangeability of parts, are not .[.desired.]. .Iadd.designed .Iaddend.to have the abrasive surface changed after prolonged usage, and generally do not .[.pro, de.]. .Iadd.provide .Iaddend.simple and effective cleaning implements. Significantly, these abrasive attachments are not adapted for use with the .[.buttery.]. .Iadd.butterfly .Iaddend.sponge mop designs which are currently in use.

SUMMARY OF THE INVENTION

It is the object of the present invention to overcome the limitations and disadvantages of prior butterfly sponge mops and mop attachments.

It is another object of the invention to provide a butterfly sponge mop attachment with an abrasive cleaning surface, which attachment can readily and easily be removed from the head of a butterfly sponge mop.

It is a further object of the invention to provide a butterfly sponge mop attachment with an abrasive cleaning surface, which attachment is designed and formed to be readily used with existing butterfly sponge mops.

It is still another object of the invention to provide a butterfly sponge mop attachment with an abrasive cleaning surface, which attachment comprises a standardized unitary integral member which is interchangeable and designed and formed to be used with different butterfly sponge mops.

It is still another object of the invention to provide a butterfly sponge mop attachment with an outer abrasive surface which can readily and easily be removed and replaced.

It is a further object of the invention to provide a butterfly sponge mop with a mop attachment with an abrasive cleaning surface, resulting in a sponge mop which is compact, lightweight, easy and flexible to use.

The present invention comprises a butterfly sponge mop which is used for routine surface cleaning and moisture absorbing mopping and an integral unitary mop attachment with an outer abrasive surface, designed and formed to be used on the head of the sponge mop for cleaning more difficult and ingrained soiled surfaces. The mop attachment consists of two detent tabs which are to be inserted into the existing cutouts located in the support member of the butterfly sponge mop. The attachment also has two side holes for placement over the existing holes of the mop's support member, through which the ends of the mop's squeeze arms are inserted. In another embodiment of the invention, the mop's sponge support member is formed with the outer abrasive surface scrubber component as a single member, advantageously formed from molded plastic construction.

The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The butterfly sponge mop and its mop attachment themselves, however, both as to their design, construction, and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Butterfly sponge mop 1 consists of handle 2 connected to sponge support member 3. Lever rod 4 is pivotally attached to handle 2 at one end. A squeeze member 5, consisting of dual squeeze arms 6 and 7, is positioned through the end of the lever rod 4.

In the mop's use mode, shown in FIG. 1, the ends of the squeeze arms 6 and 7 are positioned in holes 8 and 9, located on both sides of the support member 3. Sponge component 23 is connected to base plate 10, on which support member 3 is mounted. Base plate 10 is pivoted by spring action, which is a well known feature in the butterfly sponge mop industry.

Support member 3 has two cut-outs 11 and 12, best shown in FIGS. 2, 10, and 11. These cut-outs are designed to receive detent tabs 14 and 15 located on mop attachment 13. Mop attachment 13 is an integral unitary body which also consists of an attachment surface 16, which could be Velcro™ or similar material. This surface 16 is located on the front section 20 of the mop attachment. Removable outer abrasive surface strip 17 is attached to surface 16.

Mop attachment 13 has two holes 18 and 19 through extending rear section 21 of mop attachment 13. In the mop's use mode, shown in FIG. 1, the ends of squeeze arms 6 and 7 are positioned through holes 8 and 9, located on either side of the support member 3, and then through holes 18 and 19 of the mop attachment 13, as more fully set forth in detail below.

Mop attachment 13 can easily be attached to sponge mop 1 by first manually pivoting base plate 10 downward, as best shown in FIG. 2. Arms 6 and 7 are then manually squeezed together, thereby allowing removal of squeeze member 5 from holes 8 and 9 of support member 3. Mop attachment 13 is slid over support member 3 such that the detents 14 and 15 are inserted into cut-outs 11 and 12 of the support member 3 and holes 18 and 19 of the mop attachment 13 are aligned over and with holes 8 and 9 of the support member 3. Arms 6 and 7 of squeeze member 5 are once again manually squeezed together and reinserted into the back side of support member 3. The end of arm 6 is lined up with the holes 8 and 18 and the end of arm 7 is lines up with holes 9 and 19. The manual squeezing pressure on arms 6 and 7 is released, thus permitting the end of arm 6 to enter holes 8 and 18 and the end of arm 7 to enter holes 9 and 19. The mop attachment 13 is thereby securely attached to support member 3 and thus sponge mop 1.

Removal of mop attachment 13 is easily accomplished by pivoting base plate 10 downward, squeezing arms 6 and 7 together, removing squeeze member 5, and sliding mop attachment 13 off support member 3.

In the use mode, the sponge mop can be employed in the usual fashion, with sponge 23 being used to clean or absorb moisture from horizontal, e.g. floor, surfaces. Should there be a need for more concentrated scrubbing action, e.g. when a deep-seated or ingrained soiled area is encountered, the mop can simply be flipped over and the abrasive surface 17 of the mop attachment 13 used for cleaning.

When the mop attachment 13 is in place in support member 3, an integral unitary component is formed, as shown in FIG. 11. In an alternate embodiment, this component, made up of mop attachment 13 and support member 3, can be made as one solid piece. This single piece component and its use on the sponge mop are shown in FIGS. 12, 13, and 14.

Specifically, FIG. 12 shows cleaning implement support member 24, which is a single component of unitary construction. It supports the cleaning implements of the mop, the sponge 23, by means of base plate 10, and the outer abrasive surface strip 17, located on attachment surface 27. Support member 24 is most advantageously formed as a one piece molded plastic component, by well known injection molded construction processes.

Support member 24 consists of a forward section 25, the outermost surface of which comprises attachment surface 27. As best seen in FIG. 13, rearward section 26 of support member 24 consists of side surface 29 with hole 30 therethrough and opposite side surface 31 and hole 32 therethrough. The bottom of rearward section 26 comprises channels 33, 34, and 35. As shown in FIG. 14, the baseplate 10 of the sponge mop is connected to support member 24 by means of a spring member 36, which is positioned within the central area of channel 34. The use of such spring members in this manner is common to pivoting butterfly sponge mops.

Tubular section 37 is an integral part of support member 24 and is upstanding from rearward section 26. It is adapted to connect with handle 2 of the sponge mop. Tubular element 37 can be designed to be inserted and tightly fit into the handle or, alternatively, the handle can be inserted into the end of the tubular element.

In the mop's use mode, support member 24 is secured to base plate 10 with the known spring means 36, as described above. Squeeze arms 6 and 7 are squeezed together and positioned in channels 33 and 35 respectively. The ends of the arms then are positioned through holes 30 and 32, located on opposite side surfaces of support member 24. After the squeeze arms are released and their ends are resting within the holes 30 and 32, the mop is ready for use with its sponge and scrubber components, in the same manner as was previously described for the embodiment shown in FIG. 1.

Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
